ML2201-XXX
NOTES ON USAGE
Type of the Built-in D/A Converter
ML2201 has the built-in current-output type D/A converter and thus the design of analog output circuit is different
from the one with a voltage-output type D/A converter (e.g. MSM6650 family).
ML2201’s D/A converter is designed as current attraction type with the same circuit configuration with the one
used on MSM9831. So, the analog output circuit is different from MSM9800 family that uses a current discharge
type D/A converter. (See the table below)
